Question

I can't install Facebook Messenger on my Nokia N8

Answer 1

For Nokia N8 Facebook Messenger is not available as a standalone application. Instead you can use FMobi which is practically the same thing. You can install it from the Ovi Store page and best of all it's compatible with your phone.

Answer 2

fmobi,friendchat,im,ebuddy,nimbuzz... And many other apps are known for all around the world but they aren't the same as fb messenger,they aren't provided with stickers,widget feature,voice msgs as in android...
A devise like c7 and n8 must have an officiall fb messenger in store.
I'm wondering why c3 has fb messenger while n8 doesn't have one ??!
This is weird somewhat :/
